To all whom it hwy concern.-

Belt known that LCHARLES BURTON Wool)- BURY, a-citizen of the United States,residing at Washington, District of Columbia, have inarranged to be or key-holdin g pivott inserted from the outside of tube D through a hole matehing with the holes in the lock, and this barrel or keyholding pivot has a channel cut around itarranged so that when pushed in a springpart. I on the lock will fall into this channel and lock it in so it eannot'be removed. 7 "lhelock has a lock-bar L, whieh is mounted i on a pivot P so as to turn This invention consists in the construction cated by dotted lines in Figs. and arrangement of parts t0 form an' .im-i and unlock the bicycle by engaging with or proved looking-bicycle in'which the look may] passing'botweeu the cog-teeth C of shaft B, be readily removed for repair or exchange, so as to prevent the shaft from'turning, or by moving out from between them to release shaft, so the bicycle will be free for use. The lever L is held in one projections L on its sides,whic-h fit against M on tumbler-pieces M, mounted projections on the pivot l on each side of'lever L. There in Bicycle-Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othillustrated in the accompanyingdrawings, in

Fig. 2 is a ll, taken on aplane at rig it angles thereto Figs. 2), l, 5, and 6 show the locking-parts in different- .positions and relations. Fig. 7 shows the two I Fig. 8 [allows the end of one of the frame-tubes with notch f0l' (}llg21glllg with the lock. Fig, J shows spring used in the lock. Fig. 10 shows part of the hivyeloframe with key-inlet and re nforce-collar.

The bicycle is made'm any suitable style,

A, in which the frametubes forma junction upon a eross-tulmlar part arranged to holdthe pedal-shat t ll. 'lhis bler-picccs' M r-hat may be desired, one; on each side or more. The tnmblenpieees M are mounted in the look-shell so as to move freely in'guidos in it lengthwise and have slots to 'lit ov or pivots P to admit being raised to allow the lock-bar L to be turned to look or unlock, and then moved down wilh parts M on one side or the other bar in place.

The tumblenpieees M are held down'by springs S above and have oval'l'ceyholos ar ranged so that when the proper key' is inserted and turned they will be raised against the springs S,so as to lil'tpoinls Id off of points L on the lock-bar L to let it turn.

The tui'nblonpieces ill have their koyholes oval, more or less, so the key will liftihom by turning, so as to free the look-bar L, wh'u'h by the same motion will be moved into. or out of engagement wilh'cogs U of the pedal-shall 'eogs C, inelosed within such pedal-shall tube outside, and the branclr tube l) is located opposite these cage and contains thelock arranged to engage them.
